Bug#758666: renpy: fails to save screenshot

[Roy Clark]

Package: renpy
Version: 6.17.6-1.1
Severity: normal

Dear Maintainer,

Ren'Py fails to save screenshot images.

Step to reproduce:
1. Run a renpy game, for example the_question from renpy-thequestion pacakge.
   Or run on third renpy game, for example Katawa Shoujo:
      $ renpy '/path/to/Katawa Shoujo-linux-x86' 
2. Press 's' key to take a screenshot.
3. A message "Saved screenshot as /usr/share/games/renpy/screenshot0001.png." 
   appear in top of screen. No output in stdout or stderr when run in terminal.
4. There is actually NO screenshot0001.png saved in /usr/share/games/renpy/.

If change permission of /usr/share/games/renpy/ to drwxrwxrwx, screenshot image 
will be saved.

It seems due to that renpy save screenshots into the directory contained 
renpy.py**, which in Debian is /usr/share/games/renpy/ and normal user can 
not write files into there.

Best regards,
Roy Clark

  ...
  The save location for screenshots has now been standardized. It is now
  the directory containing the executable used to start Ren'Py, be it a
  .exe, .py, .sh, or .app. (The latter is handled specially.)
